INDEXING DEVICE Filed May 20, 1950 INVENTOR FRED R. SGHULZ ATTORNE? Patented Apr. 20, 1954 INDEXING DEVICE Application May 20, 1950, Serial No. 163,145

4 Claims. 1..

This invention relates. to-indexing-devices of the snap-on type for use-in connection with filing sheets, folders and thelike to identify,- mark or characterize the-same. More pa-rticularly,,the invention deals .with' adevice of the character describedcomprisinga pair-0f hingedly coupled parts havingangularly: disposed indexing portions with attaching or. mounting end portions having means for piercing thewsheet to which the device isattached in securi-ngthe .deviceagainst displacement fromsaidzsheet. Still more particularly, the invention deals with'a' device of the character described having'meansreta-ining the parts against displacement from: a: supporting sheet.

The novel features of the-invention will be best understood from the following description, when taken together with'the accompanying drawing, in which certain embodiments of the invention are disclosed and, inwhich, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1 is a perspective view of the upperportion of a supporting sheet, showing one of my improved devices arranged thereon" and omitting the indexing or name card or plate.

Fig. 2 is a side and sectional View of Fig. 1, the secticnbeing substantially on the line. 2"2iof Fig; 1.

Fig. 3 is an enlarged sectionalidetail viewofithe line .t'3"ofiFig. 2.

Fig. 4 is an enlarged section onthe line,4-d of'l ig; 2; and

Fig. 5 is an enlarged" section on the line 5-5 of Fig. 2.

Considering Fig. 2 of thedrawing, it will appear that my improved indexing, labeling or marking device comprises two sheet metal parts which, for purposes of description, will be identified as a front part I0 and back part I I. These parts are generally rectangular in form and include upper angularly offset portions I2 and It, respectively, said portions being substantially parallel when the device is in assembled relationship, as seen in Fig. 2.

The offset portion I2 has a large rectangular opening It for visibility of a name plate or card arranged between the parts I2 and 53; whereas the part I3 has an elongated fingerpiece opening I 5 to adjust the position of the card.

The upper offset wall portion I2 includes rearwardly extending file flanges I6, both of which are of the same construction, these flanges having, near the upper ends, apertures I? for the reception of laterally extending pintle portions 2-,. I8 on the part I3: Note'Fig; 4.; The zpintlecportions iii are of such sizeasto-freely rotateintthes apertures I'I. Theyflanges lfi alsoi'havwnear. their lower ends, angularlyy disposed; inwardly,

has abruptly bevelled, corners, as at-.20,-.-. whereas.

the corresponding corners of the-rear plate II: are simply rounded, as -indicated.-at-;2:l:- but'proetrude beyond the bevelledcornersifl soiasito. allow a finger to bepressedragainst the-corners 2I in separating the parts Illnand II,.whenit- .is-

desired to removethe same, from a.- supporting card or sheet 22.

The lower end..portion.of the-front wall 20:

has two elongated andJQngitudinalIy extendingapertures 23 andthe plate I9 above andbelow the; apertures 23 have, elongatedoutwardly pressed beads or ribs Zfikwhich reinforcethe lower end ofthe plate. Ic .and, at.the-sametime, form raised guards to protectthe fingersotthe hand.

from engaging the-prongs 25 fashioned from :the material of-the backplate-I Land extending forwardly. atright angles thereto.

Considering Fig. 5, of the drawing, it will.appear that the-prongs 25 have slightly, conical. outer ends, as at 2,5, to provide ashear-like action.

in piercing the support ormounting sheet-22..

In the use. of the device, thefront:platedllds arranged upon the upper edgehofv asupporting sheet, such as the sheet .22;.withthe lower edge. of the flanges llresting; upon or, adjacent the upper edge of the supporting sheet andwith a suitable indexing or marking card disposed upon the inner surface of the ofiset wall I2; after which, the rear plate II is swung forwardly on the pivot pins IS, in which operation, the prongs 25 pierce the sheet 22 and extend into the apertures 23. This completes attachment of the device to the supporting sheet.

In the above described operation, the ofiset wall it, or the side edges thereof, frictionally pass over the retaining or latching members l9, which members serve to hold the parts I 0 and I l against accidental displacement from the support. When the occasion should arise to remove the device from the support, the plates I0 and II are sprung apart against the resistance of the stop or check members I 9, as will be apparent.

It will appear from a consideration of Fig. 1

of the drawing that the lower and side edges, as well as the edges of the bevelled portions 20, are turned rearwardly or bevelled, as indicated at 27, so that no sharp edges will prevail upon the surface of the device. It will also be noted that the upper edge of the front ofiset wall 12 is rounded rearwardly, as indicated at 28, in Fig. 2 of the drawing, and also illustrated in Fig. 4.

It will be understood that my improved indexing, marking or labeling device can be utilized not only for atachment to a card or folder, but can also be used to secure or attach sheets to the card or folder or, in fact, in attachment of a plurality of sheets. The capacity of the device will depend entirely on the length of the prongs and depth of the side flanges [6 of the device.

Having fully described my invention, What I claim as new and desire to secure by Letters Patent is:

1. A device of the character described, comprising two hingedly coupled plates, one plate having, at its upper portion, an elongated aperture for visibility of a name card disposed between the plates rearwardly of said aperture, said upper portion of both plates being angularly ofiset, the other portion of one of the plates having spaced slits and the other plate prong members movable through said slits in attachment of the device to a supporting sheet disposed between said plates, frictional means for retaining the plates in assembled relationship to each other on a supporting sheet, said last named means comprising flanges on side edges of the upper portion only of one plate overlying corresponding edges of the opposed plate, and catch devices upon the flanges engaging side edges of the last named plate.

2. A device of the character described, comprising two hingedly coupled plates, one plate having, at its upper portion, an elongated aperture for visibility of a name card disposed between the plates rearwardly of said aperture, one of the plates having spaced slits and the other prong members movable through said slits in attachment of the device to a supporting sheet disposed between said plates, frictional means for retaining the plates in assembled relationship to each other on a supporting sheet, said last named means comprising flanges on side edges of one plate overlying corresponding edges of the opposed plate, catch devices upon the flanges engaging sideedges of the last named plate, said catch devices being in the form of inwardly pressed beads arranged angularly on said flanges, and the plate having theslits therein having raised wall portions adjacent said slits.

3. A device. of the character described, comprising two hingedly coupled plates, one plate having, at its upper portion, an elongated aperture for visibility of a name card disposed between the plates rearwardly of said aperture, one of the plates having spaced slits and the other prong members movable through said slits in attachment of the device to a supporting sheet disposed between said plates, frictional means for retaining the plates in assembled relationship to each other on a supporting sheet, said last named means comprising flanges on side edges of one plate overlying corresponding edges of the opposed plate, catch devices upon the flanges engaging side edges of the last named plate, said catch devices being in the form of inwardly pressed beads arranged angularly on said flanges, the plate having the slits therein having raised wall portions adjacent said slits, and free edges of said flanged plate being turned inwardly.
